Title: Cam device of 4-cycle engine
Inventor: KATOU AKIRA
IPC: F01L13/00
Filed: 1982-02-01
Abstract: PURPOSE:To improve both fuel consumption performance at low and medium speeds and output performance at a high speed, by adjusting a lift amount of a valve body in accordance with a change of speed of an engine in a valve rocker driving system for intake and exhaust of the 4-cycle engine. CONSTITUTION:Oil passages 43 are provided in a cam shaft 26 to feed lubricating oil 44 from the passage 43 into a fitted hole 31 of a cam 22. The cam 22 is moved by pressure of the oil 44. Because pressure of the oil 44 is changed in proportion to speed of an engine, the cam 22 can be moved to the diametrically outside direction 41 in accordance with an increase of the speed of the engine. Further here to prevent movement of the cam 22 only by centrifugal force acted on a top part 22b, the necessity for providing a mass balancer to a bottom part 22a of the cam 22 may be sometimes caused. In this way, fuel consumption performance at low and medium speeds and output performance at a high speed are both improved.
